On living large in the 1980s, riding his "Back to the Future" and "Family Ties" fame:

"I went from girls not giving me the time of day to reading it off their bedside digital clocks. It was pretty cool."

On realizing he was an alcoholic and deciding to get sober:

"It was like snapping to and saying ..., '[T]his isn't the preview. This is the movie. And I'm already well into the first big plot twist,' which is that I was going to lose all of this stuff. I had a great marriage and a great son, and I didn't want to blow that."

On being sober for 21 years:

"My sobriety is old enough to drink."

On how Parkinson's has changed his approach to acting:

"I used to be really nervous and sit in my dressing room and fret about a scene that was coming up ... now it's just like, 'OK, what's happening?' And if something happens, I react to it and if nothing happens, I don't react. I don't worry about that bit I was going to do or the look I was gonna give because when I get there I may not be able to give that look or do that thing or move that glass."

On not worrying about the future:

"These little koans and sayings that I toss off are hard-earned bits of wisdom, and one of them is that if you imagine the worst-case scenario and it happens, you've lived with it twice."
